OpenAI is trying to extend human life, with help from a longevity startup

OpenAI says it trained a new AI model called GPT-4b micro with Retro Biosciences, a longevity science startup trying to extend the human lifespan by 10 years, according to the MIT Technology Review.

Retro, which is backed by Sam Altman, has been working with OpenAI for roughly a year on this research, according to the report. The GPT-4b micro model tries to re-engineer proteins — a specific set called the Yamanaka factors — that can turn human skin cells into young-seeming stem cells. Retro believes these proteins are a promising step toward building human organs and providing supplies of replacement cells.

The model differs slightly from Google’s Nobel prize-winning AlphaFold, which predicts the shape of proteins, but it appears to be OpenAI’s first model that is custom-built for biological research. OpenAI and Retro tell the MIT Technology Review they plan to release research on the model and its outputs.

Mapping the Link Between Personality and Cognitive Decline

Summary: A new study has identified three psychological profiles that influence brain health, cognitive decline, and dementia risk in aging adults. Profiles with high protective traits, like purpose and openness, show better cognition and brain integrity, while those with low protective traits or high negative traits face accelerated brain atrophy and mental health issues.

Researchers emphasize comprehensive psychological assessments to tailor interventions, like therapies that enhance life purpose or reduce distress symptoms. These findings pave the way for personalized strategies to prevent cognitive decline and support brain health in adulthood and aging.

Geoff Hinton — Will Digital Intelligence Replace Biological Intelligence? | Vector’s Remarkable 2024

Vector Institute’s Remarkable 2024 | Geoffrey Hinton — Will Digital Intelligence Replace Biological Intelligence?

In this profound keynote, Vector co-founder Geoffrey Hinton explores the philosophical implications of artificial intelligence and its potential to surpass human intelligence. Drawing from decades of expertise, Hinton shares his growing concerns about AI’s existential risks while examining fundamental questions about consciousness, understanding, and the nature of intelligence itself.

Geoffrey Hinton is one of the founding fathers of deep learning and artificial neural networks. He was a Vice President and Engineering Fellow at Google until 2023 and is Professor Emeritus at the University of Toronto. In 2024 Hinton was awarded the Nobel Prize in Physics.

Key Topics Covered:
• The distinction between digital and analog computation in AI
• Understanding consciousness and subjective experience in AI systems.
• Evolution of language models and their capabilities.
• Existential risks and challenges of AI development.

Timeline:
00:00 — Introduction.
03:35 — Digital vs. Analog Computation.
14:55 — Large Language Models and Understanding.
27:15 — Super Intelligence and Control.
34:15 — Consciousness and Subjective Experience.
41:35 — Q\&A Session.

Gaia’s Farewell Gift Is The Best Milky Way Map We’ve Ever Seen

We can judge the value of any scientific endeavour based on how much of our knowledge it overturns or transforms. By that metric, the ESA’s Gaia mission is a resounding success.

The spacecraft gave us a precise, 3D map of our Milky Way galaxy and has forced us to abandon old ideas and replace them with compelling new ones.

Currently, we’re marking the end of the Gaia mission, our best effort to understand the Milky Way. Gaia is an astrometry mission that’s built an impressive map of the Milky Way by taking three trillion observations of two billion individual objects in the galaxy, most of them stars, over an 11-year period.

Six effective morning habits to lower cholesterol, according to cardiologist

Link :

Cholesterol management is key to maintaining a healthy heart, and adopting the right habits in the morning can make a significant difference. Whether it’s what you eat, how you move, or even how you start your day mentally, these small but effective changes can help improve your cholesterol levels over time.

If high cholesterol levels are a concern, incorporating specific morning routines into your daily life can provide lasting benefits. Here’s what Dr Prateek Chaudhary, senior consultant, Interventional Cardiology at Asian Hospital, suggests you should do.
